Merged on stable/queens.
This bug is present from the day one of adding volumes support to the docker-puppet script. But it has been hidden because of the order merging the config volumes. Till earlier puddle config_volume of neutron-ovs-dpdk-agent.yaml before config_volume of neutron-plugin-ml2.yaml, in which case the volumes will be added correctly. In this puddle, config_volume of neutron-plugin-ml2.yaml is merged first, and because of the bug, volumes list in other plugin is ignored. It is hard to find what triggered the order change, but irrespective of the order, the merging should happen correctly.
